Activated carbon filtration device performing filtration according to water quality situation

Abstract

The invention relates to the technical field of power plant chemical water active carbon filters, in particular to an activated carbon filtration device performing filtration according to water quality situation. The activated carbon filtration device is provided with a filtering body consisting of activated carbon and a reverse osmosis membrane and is characterized in that the filtration device consists of an outer sleeve and an inner sleeve which are connected in a sleeved mode, wherein the inner sleeve consists of a first cylinder, a connecting ring and a second cylinder, the first cylinder is connected with the second cylinder through the connecting ring, a filtering body is arranged in an annular cavity between the inner sleeve and the outer sleeve, the outer sleeve is externally provided with a sliding sleeve, the middle of the closed end of the U-shaped sliding sleeve is provided with a water inlet hole, the water inlet hole is provided with a water guiding pipe, one end of the water guiding pipe is communicated with the water inlet hole, the other end of the water guiding pipe extends into the U-shaped sliding sleeve and penetrates into the first cylinder of the inner sleeve, a column-shaped stop block is arranged at the tail end of the water guiding pipe in the first cylinder of the inner sleeve, and the pipe wall of the water guiding pipe is provided with a water outlet hole. The activated carbon filtration device has the advantages of being simple in structure, reducing investment, prolonging the service life of activated carbon, ensuring the safe operation and the like.

Description

Technical field [0001] The invention relates to the technical field of power plant chemical water activated carbon filters, in particular to an activated carbon filter device with simple structure, reduced investment, increased operating life of activated carbon, and guaranteed safe operation of equipment according to water quality conditions. Background technique [0002] As we all know, the water source used for reverse osmosis water production is mainly well water and surface water. Generally, it is filtered through a multi-media filter and then filtered through activated carbon. Because the plankton and suspended matter in the water vary greatly with the seasons, The water quality also changes with the seasons. Regardless of whether the water quality is good or bad, it generally needs to be filtered through an activated carbon filter. Continuously running activated carbon filters have a high operating cost and must be replaced every two years, otherwise the activated carbon wi...

[0002] As we all know, the water source used for reverse osmosis water production is mainly mixed well water and surface water. Generally, it is filtered by a multi-media filter and then filtered by activated carbon. Since the plankton and suspended matter in the water vary greatly with the seasons, The water quality also changes with the seasons. No matter the water quality is good or bad, it generally needs to be filtered through the activated carbon filter. The continuous operation of the activated carbon filter is very expensive, and it must be replaced every two years, otherwise the activated carbon will fail. , and activated carbon itself is easy to breed bacteria and microorganisms, which will cause secondary pollution to the security filter element and reverse osmosis membrane, which not only increases the operating cost, but also may affect the water quality
